[LARTC] Multiple interfaces thru one qdisc

[Ethy H. Brito]

Gurus

I am facing a problem controling bandwidth of a bunch of ppp leased lines.
I need to direct some ppp interfaces thru one queue for input
and other for output traffic.
I could not figure how to do it since queues are "bonded" to one "dev"
interface at "tc" command.
Is it possible to do? What could be the command syntax?
I used to do it with source routing and Alan Cox shaper's in kernel 2.0. Now
I am confused with lots of parameters and few documentation. FYI I read Linux
Adv Routing2.4 version 0.3.0.

Environment: Slackware-Current Linux w/kernel 2.4.4

Thanx a lot

	As far as I know (I have read about it, but not tested) it _is_
Round-Robin.

	I think that, perhaps, you can impose the queue discipline on
tql0 (that masters both ppps), and then set different routes using
ppp0 and ppp1. I wonder if the teql qdisc will shape the ppp0 and
ppp1 sending rate. I doubt it.

	Please, if there is anybody who knows teql well, confirm this
point. Maybe this behaviour can be changed.
